Abstract (en)
[origin: EP3173599A1] A variable nozzle mechanism for a variable capacity turbocharger includes: a first plate having an annular shape; a second plate facing the first plate and having an annular shape, the second plate and the first plate defining an exhaust gas path in between; a plurality of nozzle vanes rotatably supported between the first plate and the second plate; and an annular member inserted on an inner circumference side of the first plate. The first plate includes a front surface facing the exhaust gas path and a back surface on an opposite side to the front surface, the annular member includes a front surface facing the exhaust gas path and a back surface on an opposite side to the front surface, and a gap is provided between the first plate and the annular member, the gap extending along a thickness direction of the first plate, from a point between an inner circumference edge of the front surface of the first plate and an outer circumference edge of the front surface of the annular member.
